Description

[0002] Belt drive, also known as "belt drive", is a type of mechanical transmission. It consists of one or more belts tightly wrapped around two wheels (called "pulleys"). The two wheels are respectively installed on the driving shaft and the driven shaft. The friction between the belt and the two wheels is used to transmit motion and power.

[0003] At present, traditional belt transmission mechanisms can only transmit at low speeds. When traditional belt mechanisms transmit at high speeds, the centrifugal force generated by the belt under high-speed transmission causes the belt to stretch slightly, which in turn reduces the friction between the belt and the drive wheel, causing the belt to slip, which affects the overall transmission efficiency.

[0025] See also Figure 3-4 The tensioning assembly 53 in this embodiment includes a screw rod 531 that is laterally rotatably connected to the left side of the upper end of the receiving frame 52, a connecting bar 532 that is threadedly connected to the right side of the screw rod 531, a transmission block 533 that is fastened to the right side of the connecting bar 532 and can be slidably lifted, a corresponding connecting shaft 534 that is movably inserted into the interior of the transmission block 533, a vertical bar 535 that is installed on the outside of the connecting shaft 534 and vertically inserted into the right side of the upper end of the receiving frame 52, and a corresponding upper end of the vertical bar 535 that is sleeved and connected to the upper end of the vertical bar 535. The limiting shell 536 connected to the front and rear sides can stabilize the up and down movement of the vertical bar 535 through the limiting connection of the limiting shell 536. The bottom block 537 is fixedly connected to the lower end of the vertical bar 535 and slides against the right side of the lower end of the supporting frame 52.

The limiting ring 539 is installed on the front side of the rotating shaft 538 and can be limited against the side edge of the transmission belt 3. In this way, it is ensured that the transmission belt 3 after tensioning adjustment can still be in a stable transmission state.

[0026] The screw rod 531 and the connecting bar 532 are both installed horizontally on the upper end of the receiving frame 52, and the connecting bar 532 is inserted into the upper end of the receiving frame 52 in a horizontal sliding manner, ensuring that the connecting bar 532 can be smoothly moved left and right when driven by the screw rod 531; the middle part of the transmission block 533 is integrally provided with an inclined groove, and the transmission block 533 is connected to the connecting shaft 534 through the inclined groove provided in the middle, ensuring that the transmission block 533 cooperates with the transmission effect of the inclined groove in the middle, and can smoothly realize the up and down movement of the connecting shaft 534 during the horizontal movement process; the upper end of the vertical bar 535 A rectangular hollow is provided in the middle part, and the size of the rectangular hollow opened by the vertical bar 535 matches the size of the transmission block 533.

[0027] See also Figure 5 The cleaning assembly 54 in this embodiment includes an adhesive block 541 symmetrically arranged on the left side of the lower end of the supporting frame 52, a sponge layer 542 adhered to the inner side of the adhesive block 541, and the sponge layer 542 is in contact with the upper or lower side of the transmission belt 3, and a clamping strip 543 correspondingly installed on the right end of the adhesive blocks 541 on both sides, a clamping groove 544 symmetrically opened on the left side of the lower end of the supporting frame 52 and connected to the clamping strips 543 on both sides, and a spring sheet 545 fastened to both sides of the inside of the clamping groove 544 and connected to the outer side of the clamping strip 543. Through the elastic force of the spring sheet 545, the installation and cleaning of the adhesive blocks 541 and the sponge layer 542 on both sides can be quickly realized.

[0028] Among them, the adhesive block 541, sponge layer 542, card strip 543, card slot 544 and spring sheet 545 are all symmetrically arranged along the left side of the lower end of the supporting frame 52, and the upper and lower ends of the card strip 543 are concave, ensuring that the card strip 543 cooperates with the upper and lower concave parts to ensure the firmness of the docking and cleaning state; the spring sheet 545 is symmetrically arranged along the inside of the card slot 544, and the spring sheets 545 on both sides are arc-shaped strips, so that the spring sheet 545 can achieve fast elastic locking and convenient disassembly.

[0029] Here’s how it works:

[0030] When the high-speed belt transmission mechanism is to be used, the driving wheel 2 and the driven wheel 4 are first installed on the left and right sides of the connecting plate 1 respectively. Then, the transmission belt 3 is connected to the outside of the driving wheel 2 and the driven wheel 4. In this way, the driving wheel 2 and the driven wheel 4 can be connected in series to realize the rapid formation of the high-speed belt transmission mechanism. When the driving wheel 2 is rotated by the external driving device, the transmission belt 3 connected on the outside can be coordinated to realize the synchronous rotation of the driven wheel 4 connected on the right side. In this way, the transmission belt 3 as a whole can rotate at high speed to meet the subsequent transmission requirements.

[0031] In order to avoid the transmission belt 3 from slipping during the transmission process, the present application sets a multifunctional device 5 on the rear side of the connecting plate 1. That is, during the high-speed transmission process, when the transmission belt 3 slips, the screw 531 connected to the left side of the upper end of the supporting frame 52 can be rotated. As the screw 531 rotates, the connecting bar 532 threadedly connected to the right side of the screw 531 will move rightward and synchronously move the transmission block 533 connected to the right side to the right. As the transmission block 533 moves rightward, the transmission belt 3 can be connected to the transmission block 533. The connecting shaft 534 connected to the inclined groove provided inside the movable block 533 will move vertically upward along the inclined groove to realize the vertical upward movement of the vertical bar 535 connected to the outer end. When the vertical bar 535 moves upward, the upper end of the limiting sleeve 536 cooperates to enable the vertical bar 535 to move upward stably as a whole. As the vertical bar 535 moves up and down, the bottom block 537 connected to the bottom of the vertical bar 535 will realize the upward pull of the rotating shaft 538 connected to the front side, so that the rotating shaft 538 moves upward to pull up the middle part of the transmission belt 3. The transmission belt 3 is kept in a straight state to ensure the tightness of the connection between the transmission belt 3 and the outer sides of the driving wheel 2 and the driven wheel 4, so that the driving wheel 2 and the driven wheel 4 drive the transmission belt 3 to transmit at high speed without slipping. Secondly, the limiting ring 539 provided on the front side of the rotating shaft 538 can ensure that after the transmission belt 3 is pulled up, it is not easy to slip during the transmission process. The limiting ring 539 can be used to limit and block to ensure the original high-speed transmission state. When there is no need to perform high-speed transmission, the screw 531 can be reversed to achieve the leftward reset of the connecting bar 532 and the transmission block 533. In this way, the connecting shaft can move along the inclined groove again to achieve the downward reset of the vertical bar 535 as a whole. Therefore, the rotating shaft 538 installed on the front side of the bottom block 537 can release the pulling effect on the middle part of the transmission belt 3, so that the transmission belt 3 is reset to the state before being pulled up. Furthermore, the tension of the transmission belt 3 can be flexibly adjusted according to different transmission conditions to reduce the transmission slip problem and ensure smooth and stable transmission.

[0032] Secondly, during the transmission process of the transmission belt 3, dust adhesion is more likely to occur. The adhesion of dust will increase friction and wear, resulting in a greatly shortened service life of the transmission belt 3. For this reason, a cleaning component 54 is provided on the left side of the lower end of the receiving frame 52, that is, adhesive blocks 541 symmetrically arranged above and below, which are respectively provided on the upper and lower sides of the transmission belt 3. In this way, the sponge layers 542 docked on the inner sides of the adhesive blocks 541 on both sides can be offset against the upper and lower sides of the transmission belt 3 to scrape and clean the dust attached to the outer side of the transmission belt 3 during the transmission process of the transmission belt 3, so that the transmission belt 3 is not affected by dust and the overall service life is improved. When the sponge layer 542 needs to be replaced, it can be directly removed from the outside. Pull the adhesive block 541 to move the card strip 543 out of the slot 544. At the same time, the upper and lower recessed areas of the card strip 543 cooperate to quickly release the lock between the card strip 543 and the spring piece 545 to achieve a quick disassembly effect. After completing the replacement of the sponge layer 542, the card strip 543 can be reinserted into the slot 544. During the insertion process, the card strip 543 pre-extrudes the upper and lower spring pieces 545. When the recessed areas on the upper and lower sides of the card strip 543 are opposite to the spring pieces 545 on both sides, the spring pieces 545 on both sides will quickly rebound and be stuck in the recessed areas on both sides to quickly realize the insertion and locking of the card strip 543, thereby ensuring the stability of the adhesive block 541 when it is reinstalled for cleaning.
